How to flash image?

This page cover the process to flash a new operating system onto a AI Camera Dev Kit device.

The process to flash one of these device is slightly different to the process to flash a NEON-2000-JT2 device. To flash a dev kit you need to flash both the internal eMMC and external storage device. The internal eMMC device hosts the bootloader and kernel, the external storage device hosts the operating system and Jetpack.

Other useful information about flashing a Jetson based device can be found here.

Step 1: Download image to your host pc with Ubuntu

AI Camera Dev Kit

microSD image
- Jetpack 4.6.1
- backup link
- MD5:C417A00B3BD500A617D201BC9B9D4421

Checksum

Check the md5 checksum to make sure image file is correct

Linux
```
$ md5sum [file]
```
```
$ md5sum AI_Vison_DEV_kit.zip
```
Windows 10
```
$ certutil -hashfile [file] MD5
```

$ certutil -hashfile AI_Vison_DEV_kit.zip MD5

Step 2: Flash microSD card image

To flash the microSD card you are going to need the following:

microSD of at least 32GB
microSD card reader

Make sure to use a high quality microSD card to prevent corruption

Unzip the microSD zip file downloaded in Step 1 to get a .img file
```
unzip AI_Vison_DEV_kit.zip
```
Clone image file to microSD card using one of the following methods
- Ubuntu Disk Manager
  - Video of process to clone image to microSD card
  - Steps:
    1. Format disk with GPT partitioning
    2. Create a volume on the disk of type Ext4
    3. Restore image to SD card
- Linux or Mac using sudo dd if=<image file>.img of=/dev/sdX bs=4M conv=fsync
- Windows using Win32 Disk Imager
- Linux, MacOS or Windows using Balena Etcher
Insert SD card into the NEON camera
